I Applicatie: led A ugust 10, 1967-- Serial No. 388,056. k

T 0 all -z/:hom it may concern:

Be it known that I, WILLIAM R. WARREN, a citizen of the United States,residing at New York, in the county of New York and State of New York.have invented new and useful Improvements in Conveyers for Granu'latols,of which the following is'a specification.

This invention relates to means for collee-ting and removing to adesired spot the products of a granulator, such as is used forgranulating molten slag made in a. blast furnace or otherwise.

By means` of this invention material is carried in a less compact formthan is usual in the ordinary conveyers and is thereby Capable of moreuniform h vdration andaeration.

This invention is set forth in the following speciiication and claim.and illustrated in the annexed drawing in which Figure 1 is plan viewpartly in section. Fig, 2 is a side elevation partly in section. Fig. 3is a section along :c Fig. 1.

A `gran'ulator such as that described in United States Patent 151821609,issued 29 May 1906 to Heinrich Colloscus of Berlin Germany, may be usedin producing the granulation. I do not claim any device for granulationproper, but merely for the hyl1ation. aeration and proper handling ofthe material after the granulation has taken place.

In the drawingr is shown a rotary drum fr, such as is described in theCollosens patent above mentioned. Above and below the drum are platformconveyers b and c, which move like a belt and at the sides of the drumare also similar platforms d. These plat- `forms. or movable walls oriloois, are made to travel in the saine direction as the rotation of thedrum, or in the direction of its uppermost point. At the ends of thespace inclosed between the four walls, are constructed one or morestatioi'ia'ry or movable platforms or walls c.. The molten sla-g orsupply is delivered` by a conduit f to the drum. The rollers` g for thebelts can be placed in any varied or desired position for A the desiredinclination.

i Patented Aug. 4, 1908.

The` drum as described in the Colloseus p atenthas a corrugated surface,withlongitudinal slits through whichan aqueous solution of salt isthrown by a centrifugal force against -the pellets of molten slaO. Asthe pellets oislag are thrown from the corrugated surface of thegranulator they strike the walls, roof and floor of the granulatorhousings. With these housings as at present constructed the materia-lcollects in considerable masses in different parts of the chamber andcannot be removed with regularity nor can a subsequent process ofhydration and aeration be accomplished with definite certainty in ratioto volume. It is for this purpose that one or more of the four wallsofthe chamber are claimed by me to be an improvement, in that they removethe pellets 1n a continuous manner. 4The housing formed by the walls b,c, d, and by the end or ends e, catches the molten pellets thrown fromthe granulator, and 'moves them in a direction away from the granulatorin a regularly distributed volume to a point where they may be hydratedor aerated, and conveyed to a point from which they may be disposed ofas desired.

llf'hat I claim is 1. In a granulator, a housing formed `of movablebot-toni, top and sides.

2. A granulating drum combined with a housing formed of movable bottom,top and sides, the said bottom, top and sides being made to travel in adirection away from the drum.

3 In a granulator, a frame or suitable support supplied with rollers orwheels made to carry movable top, bottom and sides, such supports andwheels being placed so as to hold the housing parts in the desiredposition.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
